AA was good at rebuilding the farm system - but he also played under different rules and he exploited those rules (kudos to him) to give himself 2-3 times more top draft picks than Atkins (or any other GM in baseball) is able to under the new rules.
I 100% agree that Atkins has sucked at drafting/development, but AA also had advantages when you try to compare them, which should be considered in this discussion.
To be honest, even after exploding the loophole, AA's "hit" rate still wasn't great. If it was, our window may have stayed open longer than just 2015/16.
